Briefly answer the following questions: (15 points)
Describe the relationship between positive and negative feedback mechanisms
A positive feedback mechanism tends to change the process, while a negative feedback
mechanism resists the change ultimately achieving balance within the process
2. How is earth science studied?
Earth science is typically studied by investigating the interrelationship between the
various open systems of the earth (biosphere, lithosphere, hydrosphere and atmosphere)

Plate tectonics, oxygen atmosphere, life, water in three states, soil accumulation, our
distance from the sun, etc…..
